Abstract (en)

[origin: WO2022072075A1] An assembled grid tray is disclosed, comprising a frame for holding multiple substrate trays to form a larger tray for use in a semiconductor processing tool. The frame may be comprised of two outer frame members that hold one or more of the trays, each with a magnet rail use with a maglev system. The frame may be further comprised of an inner frame member positioned between the outer frame members, which may also include a magnet rail, with the frame members being held in position by one or more outer beam members. The frame members may be fabricated of a material having a similar thermal expansion to trays to be placed in the frame.
